The influence of dietary nitrogen and phosphorus on Cd accumulation in the woodlouse Porcellio scaber Latr
Bioaccumulation of potentially toxic metals by litter-feeding invertebrates is determined not only by the concentration of metal in the diet, but also by the flux of food through the body. Nitrogen and phosphorus are the main elements regulating food consumption and so are expected to affect the bioaccumulation of trace elements such as cadmium. To test this idea, we applied a three-factor orth...
متن کاملAn interesting variety
This issue of Neurology ® : Neuroimmunology and Neu-roinflammation (N2) includes a wide variety of exciting articles. As usual, I had difficulty selecting the articles to highlight in this Editor's Corner, which is aimed to reflect the range of topics rather than imply a higher quality of the selected manuscripts. One of the treatments frequently used in neuro-myelitis optica (NMO) is rituximab...
متن کاملPersonality affects defensive behaviour of Porcellio scaber (Isopoda, Oniscidea)
We evaluated individual behavioural patterns of isopods expressed as tonic immobility following some intrusive treatments. Common rough woodlice, Porcellioscaber, were kept individually in plastic boxes and tested for tonic immobility repeatedly. Reactivity, sensitivity (number of stimuli needed to respond), and endurance of tonic immobility (TI) according three types of treatments (touch, sque...
متن کاملTransformations of mercury in the terrestrial isopod Porcellio scaber (Crustacea).
The biological cycle of mercury in the terrestrial isopod Porcellio scaber was investigated. Testing the possibility of in vivo Hg(2+) methylation was divided into two methodologically different parts. Firstly, concentrations of total mercury and MeHg in isopods P. scaber and their environment from a Hg-unpolluted area were measured by the use of validated methods (CV AAS, CV AFS). The data obt...
متن کاملPorcellio scaber algorithm (PSA) for solving constrained optimization problems
In this paper, we extend a bio-inspired algorithm called the porcellio scaber algorithm (PSA) to solve constrained optimization problems, including a constrained mixed discrete-continuous nonlinear optimization problem. Our extensive experiment results based on benchmark optimization problems show that the PSA has a better performance than many existing methods or algorithms. The results indica...
